ESG has contributed significantly to some of the most complex environmental cleanups in Canada. Often working in remote parts of Canada, using processes developed by our team, our award-winning group has become a leading authority on the investigation, remediation and monitoring of contaminants in the environment.
See what we do and who we areESG develops scientific guidance for the long-term management of terrestrial and aquatic sites, for practitioners and site owners. Through accurate data collection, we capture the site-specific information that allows us to analyze the issues and develop practical approaches for resolving them.
Federal practitioners and site owners have worked with ESG for many years because of our adaptable and flexible approach and the high quality of our work. We stay focussed on a small number of projects each year – approximately 40 – to keep our level of quality high.
The fundamental research arm of ESG educates students at the Master's, Ph.D. and postdoctoral level, with degrees granted by Queen's University (with co-supervision) and the Royal Military College of Canada. Our research encompasses environmental engineering and science aspects of emerging contaminants (PFAS, per- and polyfluoroalkyl substances), such as remediation and characterization in the environment. Our research also includes the study of arsenic transformations in the environment and bioaccessibility of various contaminants.

Some applied projects spawn questions that are investigated through fundamental research processes, and some fundamental research generates ideas that need pilot field testing. Graduate students often do field work for applied projects, and staff members conduct fundamental research on topics that complement applied projects. This flow of people and projects between fundamental research and applied projects is unique to ESG and leads to innovation.
The Royal Military College of Canada – in Kingston, Ontario – is our home base. We have about 30 employees and 10 graduate students. Most staff and students are civilians, while some staff and students are DND or CF members.
At ESG, it is possible to pursue a post-graduate degree (Master's, second Master's, or PhD), or work as an employee. Some people do both.

With our offices at RMC in Kingston as a central hub, we fully support remote work and offer flexibility to our staff. We come together for fieldwork and collaborate online to maintain strong connections and effective teamwork. Our team is gender balanced, and we foster an inclusive and collaborative work environment.
Everyone at ESG has the opportunity to travel across Canada, develop skills, work in multidisciplinary teams, and participate in innovative projects. During spring, summer and fall, many staff members and students travel to project sites to collect data. Field work involves a lot of time outside, and staff members may spend a few days or up to several weeks each year away from home, on field teams: collecting soil and groundwater samples, or monitoring species at risk, or surveying. Outside of field work periods, they help with planning; managing and analyzing data; and developing recommendations, writing reports, creating maps, or building geodatabases.
Apply to work or study with ESGNew grads gain skills in a supportive environment that encourages career growth into increasing levels of responsibility on applied projects, or a post-graduate degree under the supervision of our senior staff, or both. We also have opportunities for undergraduate interns and co-op students.
